An interventional study of ESP block group and RISS block group in Video Assisted Thoracoscopic Surgery, Regional Block for Pain Control and Regional Blocks, sponsored by Bursa City Hospital. Completed at 1 site in Turkey (Türkiye). Open to participants aged 18 Years to 80 Years. Per ClinicalTrials.gov, last updated 2026-09-24.
Sponsored by Bursa City Hospital · Not applicable, Interventional, and Treatment
To compare the rhomboid intercostal subserratus plane block with the erector spinae plane block regarding their analgesic efficacy and effects on respiratory function for patients undergoing video-assisted thoracoscopic surgery.
Video-assisted thoracoscopic surgery (VATS) can be very painful and may lead to complications such as prolonged stays in intensive care, thromboembolic complications due to lack of early mobilization, chronic acute pain, and delirium if adequate analgesia is not provided. Therefore, using thoracic epidural, paravertebral, or regional blocks as part of multimodal analgesia is recommended to provide effective pain relief.
This study aims to compare the effects of the erector spinae plane block (ESP) and rhomboid intercostal subserratus plane block (RISS) on postoperative analgesia and the improvement of respiratory parameters in patients undergoing VATS. These two techniques may have different analgesic profiles with respect to somatic and visceral pain.
The primary objective is to evaluate the incidence of chest tube-site somatic pain at postoperative hour 2. Secondary objectives include the incidence of visceral pain, total analgesic consumption in the first 24 hours postoperatively, assessing resting and dynamic pain scores, triflow performance, complications, and length of hospital stay.
Bursa City Hospital is the lead sponsor of 66 studies on the registry; 31 are open to participants now.
Counted across the registry records on this site, refreshed daily.
Exclusion Criteria:
Those who received the erector spinae plane block for postoperative pain management
Procedure: ESP block group
Those who received the rhomboid intercostal subserratus plane block for postoperative pain management
Procedure: RISS block group
ESP blocks are performed for patients undergoing VATS.
RISS blocks are performed for patients undergoing VATS.
Incidence of chest tube-site somatic pain
Proportion of participants with localized pain at the chest tube insertion site, elicited by palpation or chest tube manipulation. Somatic pain was recorded as present or absent.
Time frame: At postoperative hour 2
Dynamic pain score
Postoperative pain scores during coughing and deep breathing are measured on a 11 cm scale, where "0" indicates no pain and "10" indicates the worst pain ever.
Time frame: Postoperative first 24 hours.
Opioid consumption
Total opioid consumption within the first 24 hours in the postoperative period.
Time frame: Postoperative first 24 hours.
Resting pain score
Postoperative pain scores during rest are measured on a 11 cm scale, where "0" indicates no pain and "10" indicates the worst pain ever.
Time frame: Postoperative first 24 hours.
Pulmonary functions
Pulmonary functions are assessed using Triflow performance. Postoperative Triflow numbers (whether 1, 2, or 3 balls can be raised) for the patients are recorded.
Time frame: Postoperative first 24 hours.
Complications
Complications regarding regional blocks and surgery (such as hematoma, pulmonary complications) are recorded.
Time frame: From block administration to hospital discharge.
Hospital stay time
The length of hospital stay is recorded.
Time frame: From surgery to hospital discharge.
Incidence of visceral pain
Proportion of participants reporting deep, poorly localized intrathoracic pain not confined to the incision or chest tube insertion site. Pain was recorded as present or absent.
Time frame: At postoperative hour 2
